conromrron or new YOBK CLOSURE Application filed May 10, 1928. Serial No. 276,586.

'My invention relates to container closures and refers particularly to expansible closure means.

One of the ob'ects of my invention is a device capable o producing a tight closure jointure through expansible means Another object of my invention 1s a devlce capable of producing a tight closure without the employment of threaded means between the closure element and the receptacle.

Another objectof my invention is a closure device capable of compensating the expansion or contraction of its receptacle due to its change of temperature.

Another object of my invention is a devlce capable of producing a tight closure when the contour, or face, of its container possesses irregularities.

Another object of my invention is a device in which the closure element may be easily and economically replaced.

Another object of my invention is a device in which only a slight. revolution of its parts are necessary to form a tight closure.

While I show and describe my device as suitable for massaging purposes, I do not limit myself to such particular formation or use. a 7

Under certain circumstances it is advisable to massage the face with hot or cold devices,

during which processmore or less pressure upon the skin is desirable.

It is evident that during this operation the massaging device will rapidly change its temperature and hence become ineffective.

Further, the device should be of such construction that the contents of the device will not accidently issue therefrom causing injury to the skin.

As the temperature of the receptacle contents is usually much higher or lower than the ordinary temperature, the change of temperature to normal causes the receptacle to expand or diminish, thus produclng elther a leakage, or an undesirable bindmg, between the receptacle and the closure means when the threaded members are employed.

My invention presents a device havlng all of the above-mentioned, and other, desirable attributes, as will be evident upon a consideration of my specification and its accompanymg drawings.

Figure 1 is a top view of one form of the device of my invention. 1

Figure 2 is a section through the line 22 of Flgure 1.

Figure 3 is a side view of the device of my nvention and its receptacle.

Flgure 4 is a perspective view of the receptacle. I The particular form of the device of my nvention shown in the accompanying drawlngs comprlses an annular metallic plate 10 through which passes the fixedly attached threaded bolt 11. The bolt 11 passes also through the annular rubber closure member 12 and the annular metallic plate 13, the latter'having the two outwardly and downwardly extended locking members 14,14.

Positioned within thewooden handle 15 is a non-revoluble threaded nut 16, the bolt 11 being threaded with the nut 16, and movable within an opening 17 within the handle 15. An annular protective metallic member 18 covers the lower portion of the handle 15 and has an opening therein for the passage of the bolt '11.

The thimble-shaped' receptacle 19 has two recesses 20, 20, within the upper periphery,

.into which the extended locking members will be fitted when the closure elements bf the dewiice are placed in position upon the receptac e.

The operation of the device is as follows The desired material 21, shown. as a liquid,

is placed within the receptacle 19 and-the closure members 10, 12 and 13 are placed therein, the Lplate 13 extending over the upper edge of the receptacle 19 and the members 14, 14, fitted within the recesses 20, 20, thus preventing the revolution of these closure members. The handle 15 is now revolved, nut 16 passing downwardly over the bolt 11, bringing the plates 10 and 13 nearer together, thus compressing the rubber closure member 12 forcing it outwardly into compressed abutment against the inner face of the sides of the receptacle 19 producing a tight closure.

It is to be noted that an absolutely tight closure can thus be formed by a slight revolution of the handle, and that any expansion or contraction of the receptacle 19 because of the temperature of the ingredients can be 5 easily compensated by the handle revolution. These and the other advantages previously mentioned are evident upon a consideration o f the construction and operation of my device.

I do not limit myself to the particular size, shape, number, arrangement or material of parts as shown and described as these are given simply as a means for clearly explainm the device of my invention.

at I claim is 1. In a closure, in combination, a receptacle, having a plurality of recesses in its upper periphery, a removable lower plate within said receptacle, a resilient closure member positioned upon said lower plate abuttable upon the inner face of the receptacle sides, an upper plate positioned upon said closure member having a plurality of extended lugs placeable within the receptacle recesses and abuttable upon the upper edge of the receptacle sides, a handle positioned upon said upper plate threaded means carried by 'the handle and a threaded bolt fixedly attached to said lower plate and extending to throu b said plates and closure member and threaded with the threaded member of the handle.

2. In a closure, in combination, a receptacle, having a plurality of recesses in its 85 upper periphery, a removable lower plate within said receptacle, a resilient closure member positioned upon said lower plate abuttable upon the inner face of the receptacle sides, an upper plate positioned upon 4o said closure member having a plurality of extended lugs placeable within the receptacle recesses and abuttable upon the upper edge of the receptacle sides, a handle positioned upon said upper plate, a non-revoluble 46 threaded nut carried by said handle and a threaded bolt fixedly attached to said bottom plate and extending throu h said plates, closure member and nut an threaded within said nut.
